OG exemplary drawing
 
1. A staple cartridge assembly for use with a surgical stapling instrument, wherein said staple cartridge assembly comprises:
a compressible adjunct comprising attachment regions; and
a staple cartridge, comprising:
a proximal end;
a distal end;
a deck comprising an outer surface, wherein said compressible adjunct is configured to be positioned against said outer surface of said deck;
a longitudinal row of staple cavities defined in said deck between said proximal end and said distal end, wherein the staple cavities of the longitudinal row are positioned along a longitudinal axis extending through the proximal end and the distal end of the staple cartridge;
staples removably positioned in said staple cavities;
bonding zones, wherein said attachment regions of said compressible adjunct are configured to be secured to bonding areas defined by said bonding zones, and wherein said bonding zones are defined as portions of said outer surface of said deck longitudinally extending along the longitudinal axis between said staple cavities of said longitudinal row, wherein the bonding areas comprise a surface having a greater roughness than portions of the outer surface of the deck surrounding the bonding zones, and wherein the greater roughness of each bonding area surface is a result of a surface modification, wherein the surface modification comprises mechanical abrasion, chemical etching, shot peening, laser peening, or plasma spraying, or any combination thereof; and
barbs protruding from said deck, wherein said barbs are configured to maintain an initial alignment between said attachment regions and said bonding zones prior to attachment of said compressible adjunct to said deck.
